3 Claims.

This invention relates to cooling devices for water and the like.

An object of the invention is to provide a water cooling unit so constructed that the cost of operating and maintaining it is at the lowest minimum.

Another object of the invention is to provide a water cooling unit including a compressor driven by means of a water motor operated by water flowing to a cooling tank from a source of water such as water mains.

A further object of the invention is to provide a water cooling unit in which water flows to a water cooling tank through aY water motor which operates the cooler compressor, and in which the cooling gases circulate through pipes surrounding the water cooling tank.

Other objects and advantages of the invention will become apparent from the following description of a preferred embodiment thereof as illustrated in the accompanying drawings, and in which the ligure is a partly sectioned elevation of my improved Water cooler device.

Reference is now had to the drawings, in which like reference characters denote similar parts throughout the several views. As shown, there is a base 2 upon which is mounted a water driven motor 4 having a water inlet at 6 for allowing water to flow into the motor 4 from a pipe 8 connected to the Water main or the like, the motor having vanes I mounted Within a housing I2 for rotation on a power shaft I4 about a vertical axis under the influence of water flowing through the motor 4. The motor has a water outlet' I6 connected to a water pipe I8 which leads the water into a water supply tank 2li from which it flows in the direction of the arrow 22 to be consumed.

The water tank 20 is supported within a casing 24, the outer walls of thewater` tank being spaced from the inner walls of the casing 24, to form a chamber 26 therebetween. A cooling coil 28 or f evaporator is wound around the water tank, cooling the fluid owing into coil 28 through condenser 29 and pipe 30 in the direction of the arrow 32, and leaving the coil 28 through pipe 34 in the direction of the arrow 36.

A refrigerator compressor 38 of any standard type suitable for the purpose is mounted above the water motor 4 upon a flange 40 which is bolted Y to a ange 42 carried by the water motor housing Both anges 40 `and 42 are provided with aligned vertical bores 44 and 46 through which extends the drive shaft I4. The shaft I4 extends upward into the compressor casing 38 and is journaled in 2 is mounted upon and keyed to the shaft I4 so as to be rotatable therewith as the water motor 4 is actuated.

The rotation of the cam 54 causes the alternate reciprocation of the pistons 56 in the cylinders 58 forming'parts of the compressor casing 38, to compress the refrigerant, the pistons having built in check valves 59. It is thus apparent that the flow of water through the water motor 4 causes rotation of the shaft I4, and operates the compressor 38, thus reducing the temperature of the cooling coils 28 and hence cooling the water in the tank 28.

As is illustrated, a temperature responsive element I2 is disposed adjacent the cooling unit to control a restricter valve 14 in the refrigerant pipe 38, between the condenser 28 and evaporator 28. The outlet pipes 'I6 and 'I8 leading from the compressor lead into pipe 30 as illustrated in Figure 1. A water check valve is shown in the water pipe I 8 at 88. A T coupling 82 interposed in pipe I8, allows water flowing through the water motor 4, to flow to the water pipes 84 supplying the faucets and other plumbing fixtures in a house or building, thus gaining refrigerating effect from any flow of water therethrough. Bypass couplings 86 and 88 are connected by pipe 98 in which a control valve, not shown, is interposed, to allow water to bypass the water motor as desired. The cooling coils, tanks and containers shown will be insulated where advantageous. It will be apparent that this is a unit of great convenience and may be mounted under sinks, in basements, or in other suitable places.

Although I have described a preferred embodiment of my invention in speciiic terms, it is to be understood that various changes may be made in size, shape, materials and arrangement without departing -i'rom the spirit and scope of the invention as claimed.

I claim:

1. A water cooling apparatus including a water motor comprising a motor casing having an inlet pipe and an outlet pipe and containing a rotatable drive shaft having a. water driven rotor mounted thereon, a refrigerant pump casing supported by the motor casing and containing pumping elements operatively connected to the drive shaft within the pump casing, a Water tank supported by the pump casing and having an outlet water pipe for supplying refrigerated water, the outlet pipe from the motor casing being connected to the water tank, a refrigerating line including evaporator coils disposed in heat exchange relabearings provided therein. An eccentric cam 54 55 tion with said water tank, one portion of said reirigerating line having condensing means connected therein 'and being connected to one portion of the pump casing, another portion of said refrigerating line being connected to another portion oi' said pump casing. and a restrictor element arranged within the refrigerating line between the condensing means and evaporator coils.

2. A water cooling apparatus including a water motor comprising a motor casing having 'an inlet pipe and an outlet pipe and containing a rotatable drive shaft having a. water driven rotor mounted thereon, a refrigerating pump4 casing fixed upon the upper portion of the motor casing and containing pumping elements operatively connected to the drive shaft within the pump casing, a water tank fixed upon the pump casing and having an outlet pipe for supplying refrigerated water. the outlet pipe from the motor casing being connected to the water tank. a refrigerant line including evaporator coils disposed in heat engaging relation with the water tank and condensing coils remote from the water tank and disposed between such tank and the pump casing. and a restrictor device connected in the` refrigerant line between the condensing coils and evaporator coils. the opposite ends of the refrigerant line being connected to the opposite sides o1 the pump casing. 1 Y, 3. A water cooling apparatus including a. water motor comprising a motor casing having an inlet pipe and an outlet pipe and containing a vertically disposed rotatable drive shaft having a rotor mounted thereon and rotating therewith about a vertical axis. a refrigerating pump casing rigidly mounted upon the motor casing having cylinders with horizontally reciprocating pistons operatively connected to the drive shaft.within the pump casing. a water tank flxedly mounted upon the pump casing and having an outlet pipe for supplying refrigerated water. the outlet pipe from the motor casing being connected' to the water tank, a refrigerating line including evaporator coils disposed in heat exchange relation with the water tank, the opposite ends of the refrigerating line being connected to the cylinders of said pump casing. condensing means connected in the rei'rigerating line between said pump cylinders and the evaporator coils and remote from the water tank, a restrictor device connected in the refrigerating line between the condensing means and evaporator coils. and a easing surrounding the water tank and evaporator coils. y
